'IO ALL WHOM IT MAY CONCERN:

Be it known that I, GALEN ORR, of Needham, in the county of Norfolk, and State of Massachusetts, have invented an Improvementin Cutting out Blanks for Blind-Hooks; and I do hereby declare thatthe following is a full and exact description thereof, refe-rence being had to the accompanying drawings, making part of this specification- Figure 1 representing one end ol' a. plate of metal from which the blanks are out, as indicated.

Figure 2, a similar view, showing a slight modification of the method of cutting 4out the blanks. Figure 3, a view of a finished blind-hook, to illustrate the parts of the blanks. Like letters designate corresponding parts in all of the figures. The object of my invention is to cut out the blanks with no waste of material, and with the fewest trianipul-ations. and least labor, so as to cheepen the construction of the hooks to the utmost extent.i

To accomplish this result, the blanks are cut in pairs, B C, successively, from the plate A, the two composing an oblong strip of metal, of uniform width, across the whole width ofthe plate. They'ale separated obliquely, the overlapping parts to form they Shanks of the hooksf Then the outer ends of the blanks are divid'ed(as in iig. 1) by a right-angled cut, into two branches, the branch a, with the lapped end c, to form the braceof the hook,and the other'branch, to 'orm the pivot of the hook.V

Each pairgof blanks is cut oit by a single blow of the die, and as itis seen no waste of material is sustained, the formation ofthe blanks is reduced to the utmost economy. f

The modification, represented in iig. 2, differs from the method shown in iig. 1, in extending the branch a a' little longer in :t straight line, a'nd cutting off the end of the branch b, leaving a space, d, as shown,'instead of the bend c in fig. 1. This method wastes a little metal, but the subsequent working of the hook issomewhat expedited.

What I claim as my invent-ion, and desire to secure by Letters Patent, is- Making blind-hook blanks, by cuttingr plate-metal to the shape herein specified.
